A T3 test is a blood test that measures the level of triiodothyronine (T3) hormone in the body. T3 is one of the main hormones produced by the thyroid gland. The thyroid is a small gland located in the neck. It controls how the body uses energy and affects many important functions.
The T3 test is mainly used to evaluate thyroid function. It helps doctors understand how well the thyroid gland is working. T3 plays a role in regulating heart rate, body temperature, metabolism, and digestion. When T3 levels are too high or too low, the body may show different health problems.
Doctors usually order a T3 test when they suspect thyroid disorders, especially hyperthyroidism. In hyperthyroidism, the thyroid gland produces too much hormone. T3 levels often rise earlier than other thyroid hormones in this condition. Symptoms may include weight loss, fast heartbeat, sweating, anxiety, tremors, and trouble sleeping.
The T3 test is also helpful when TSH and T4 test results are unclear. Sometimes, T4 levels may appear normal, but T3 levels are abnormal. This condition is called T3 toxicosis. In such cases, the T3 test helps confirm the diagnosis.
A T3 test may be recommended if a patient has:
- Unexplained weight changes
- Fatigue or weakness
- Irregular heartbeat
- Nervousness or anxiety
- Sensitivity to heat or cold
The test is done using a blood sample, usually taken from a vein in the arm. No special preparation is required in most cases, but your doctor may advise stopping certain medicines before the test.
Normal T3 levels depend on age and lab standards. High levels may indicate overactive thyroid, while low levels may suggest underactive thyroid or other health issues.
It is important to interpret T3 test results along with TSH and T4 tests. This gives a complete picture of thyroid health and helps guide treatment decisions.

In thyroid what is t3 t4 test what is the best way to track hypo thyroid?
T3 is triiodothyronine, and is the active form of the hormone secreted by the thyroid. T4 (thyroxine) is another form of thyroid hormone which must be converted to T3 by your body via the deiodinase enzyme. Although T3 is active, your body produces much more T4. The best way to monitor low thyroid function is by looking at TSH (thyroid stimulating hormone). TSH will be high if the thyroid is not producing enough T3/T4. For the majority of hypothyroid cases, only TSH needs to be monitored. For hyperthyroidism and some hard to treat hypothyroid cases, the doctor will test T3 and T4.
Why are they reluctant to do the thyroid T4 test?
The old Total T4 test (TT4) is no longer considered the best way to test for T4 levels. T4 and T3 can both be bound by other proteins and hormones in the body. When this happens, the T4 or T3 is not usable by the body. The body can only use T4 and T3 that is not bound, or free. For this reason, Free T4, which only tests the free levels of the hormone, is now preferred over Total T4 testing as more accurate.
